Plplot supports bindings and test examples. To include this powerful component of PLplot for Windows you must download and install Octave for Windows.

Download the Windows Octave installer from

Run that executable (under wine that is done with the "wine Octave-3.2.4_i686-pc-mingw32_gcc-4.4.0_setup.exe command), and choose all defaults except the install prefix which should refer to a unique location so that octave can easily be removed later without interfering with anything else. In my case I chose to use Z:\home\wine\newstart\octave\Octave\3.2.4_gcc-4.4.0. In other words, I replaced the C: in the default prefix by Z:\home\wine\newstart\octave, but you are free to use anything you like. Let's call that install prefix OCTAVE_PREFIX (e.g., OCTAVE_PREFIX=Z:\home\wine\newstart\octave\Octave\3.2.4_gcc-4.4.0 in my case). Then to help cmake locate octave on your Windows machine you have to set the following environment variables:

  • PATH=$PATH:$OCTAVE_PREFIX/bin (Location of octave.exe and liboctave.dll.)
  • CMAKE_INCLUDE_PATH=$OCTAVE_PREFIX/include/octave-3.2.4/octave:$CMAKE_INCLUDE_PATH (Location of octave.h.)
  • CMAKE_LIBRARY_PATH=$OCTAVE_PREFIX/lib/octave-3.2.4:$CMAKE_LIBRARY_PATH (Location of liboctave.dll.a)

(PATH is always predefined, but in case CMAKE_INCLUDE_PATH is not predefined, then drop the trailing ":$CMAKE_INCLUDE_PATH" in that definition, and in case CMAKE_LIBRARY_PATH is not defined drop the trailing ":$CMAKE_LIBRARY_PATH" in that definition.)
